Application filed September 21, 1914:.

To all whom it may concern Be it known that I. Bonnier A. Esme, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey have invented a new and useful ell-Strainer, of which the following is a specification.

The device forming the subject matter of this application is a means whereby a strainer may be removed from the tubing of awell.

One object of the present invention is to provide av device of this type in which the fishing tool is permitted to have a longitudinal movement, thereby to jar the strainer and loosen the same, the construction being such that this jarring movement may take place without danger of loosening or detaching the fishing tool from the strainer suport.

Another object of the invention is to provide. a novel means whereby during the lowering of the tool and a rotation thereof, the tool may be interlocked with the strainer support.

A further object of the inventionis to provide novel means for centering the fishing tool with respect to the strainer support.

It is within the scope of the invention to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement, of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise ci'nbodiment otthc invention herein disclosed, can be made within the scope of what is claimed, without departing. from the spirit of the invention.

In the accompanying drawings :Figure 1 shows in longitudinal section, a portion of a strainer wherewith one form of strainer support has been assembled, the strainer support for the most part appearing in elc vation, parts thereof being broken away, and the fishing tool being shown in place; l' i 9 is a cross section on the line of Fig. 1; Fig. 3 is a cross section on the line i i--13 of Fig. 1, looking downwardly in the direction of the arrow 3; Fig. 4 is a trans- Specification of Letters Patent.

I Patented Dec. 7, 1915. Serial No. 862,837.

verse section on the line A-B of Fig. 1, looking upwardly in the direction of the arrow 4; Fig. 5 is a side elevation showing aanodified form of strainer support;-and F 1g. 6 is a sectional elevation showing both of the supports hereinbefore alluded to, as sembled with the strainer.

The strainer support delineated in Figs. 1, 3 and at is in the form of a plug which inserted into the lower end of the strainer. lhe strainer support under consideration includes a solid body portion 1, provided in its lower end with a recess 2 and having, at its lower end, an outwardly projecting lateral flange 3. The strainer 4, which is ordinarily of tubular form, embraces the body portion of the strainer support or plug closely, and rests at its lower end upon the flange 3, as Fig. 1 will make evident. Securing elements 5 of any desired sort and of any preferred number pass through the lower portion of the strainer 4 and through the lower end of the body 1 of the strainer, the inner ends of the securing elements 5 being housed in the recess 2. Owing to the construction last above described, it will be obvious that mounting and removal. of the securing elements 5 are facilitated. As will be understood best from Fig. 2, the body-portion 1 of the support is longitudinally slotted as shown at 6. In its upper end, the body por tion of the supportis provided with a circular centering bore 7, opening into the slot 6 intermediate the lateral extremities of the slot. The function of the centering bore 7 will be pointed out hereinafter. As shown at 8. the body of the support is cut away laterally, in opposite directions and upon opposed sides, to define upright standards 9 and to define oppositely projecting transverse arms 10 adjacent the upper ends of the standards 9. The upper face of the solid lower end, of the body of the strainer forms a table 11 which coiipcratcs-with' the arms 10 in a manner which will be set forth hereinafter. A fishing tool is provided, the same comprisinga shank 12 and a transverse head 14. The lower edges of the head '14. on verge downwardly as shown at 15,

t cfia-e a centering boss 16. As will be understood by those skilled in the art, the strainer 4E, commonly, is located within the well tubing (not shown).

In operation, the fishing tool is lowered and the centering boss 16 comes into engagement with centering bore 7. Then the fishing tool is rotated until the head 1 1 thereof is alin ed with the slot 6, whereupon the tool is lowered until the transverse head 14 lies below the arms 10. Then the fishing tool is rotated axially, until the ends of the head 14; lie beneath the arms 10. If the fishing tool now be drawn upwardly, it is obvious that the upper edges of the head 14 on the fishing tool will come into contact with the lower edges of the arms 10 on the strainer support, under which conditions, the strainer support and the strainer may be lifted out of the'well tubing. It is to be observed that the distance between'the lower'edges of the arms 10 and the table 11 is sufficient so that the fishing tool may be given a reciprocating motion, after the same has been turned axially to dispose the ends of the head 14 beneath the arms 10. When a reciprocating motion is imparted to the fishing tool, the boss 16 on the tool, as the latter moves downwardly, will come into contact with the table 11, and the upper edge of-the head 14:, as the tool moves upwardly, will con1e,.into contact with the lower edges of the arms 10, it being obvious that by this operation, a jar will be imparted to the strainer support and the strainer, thereby loosening these elements from the well tubing. It is to be observed, further, that this reciprocating movement of the fishing tool takes place without in anywise endangering the interlocking engagement between the fishing tool and the strainer support.

Passing to that form of the invention which is delineated in Figs. 5 and 6, the body 17 of the strainer support is of tubular form and is threaded as shown at 19, to.

engage the upper end of the strainer 18., the support under consideration being in the form of a casing. The tubular body 17 of the strainer support is provided with a longitudinal slot 20 and is cut away laterally and in opposite directions upon opposed sides as shown at 21, to define upright standards 22 and oppositely pr0 eet1ng transverse arms 23. Each arm 23 adjacent its extremity and upon its upper edge is beveled as shown at 2 1 and the opposed portion of the standard 22 is beveled as shown at 25. The lower edge of each arm 23 may be beveled at its end as shown at 26. The fishing tool embodies a shank 28, a blade 29, and a transverse head 30 proecting beyond opposite edges of the blade 29; the head 30 being equipped at its lower end with a centering boss or foot 31, the edges of which converge and extend downwardly as shown at 32. The casing 17 is assembled with the upper end of the strainer '18 as shown in'Fig. 6. The fishing L'tOOl islowered into the well and as the tool downwardly, with the lower portion of the casing to obvious from Fig; Fig. 6, the upper end of the strainer may be is lowered, the lower edges of the transverse head 30 engage the beveled edges 24 and 25 of the casing, and thus the fishing tool is centered. The tool is lowered through the slot20 and then is rotated until the ends of the head 30 lie beneath the arms 23. The fishing tool may be reciprocated, as before, to produce a jar, the necessary abutments being provided by the lower edges of the arms 23 and transverse shoulders 27 formed on the body portion of the strainer, between the standards 22. As the fishing tool moves the. foot or boss 31 cooperates center the tool and it is to be observed that when the lower edge of the transverse head 30 first comes into contact with the upper end of the casing 17, the boss or foot ,'3 1

enters within the casing and serves to center the tool, before the tool is rotated to bring the lower edges of ation with the beveledportions 24 and 25 of the casing. When the tool is being re-' moved from the casing, the beveled edges 26 facilitate such an o eration, as will be 5. s clearly shown in tea the head 30 into cotiper provided with the structure shown in Fig. 5,

the lower end of the strainer being equipped with the device depicted in Fig. 1.

Especial attention is directed to the fact that in both forms of the invention, a jar may be imparted to the strainer support, for the purpose of loosening the same, such jar being imparted without endangering the interlocked engagement between the fishing tool and the support.

Having thus described the invention, what is claimed is 1.'In a device of the class described, a strainer support having vertically spaced parts; and a fishing tool mounted to reciprocate independently of the support and including a transverse head, the tool being rotatable to dispose the head between sai whereby the head may therebetween and exert a jarthe tool has been away laterally and in opposite directions, upon opposite sides to define a table, up-' right standards, andoppositely projectin transverse arms ad acent the upper ends 0 d parts of the support, the height of the head the standards and spaced vertically from the table; and a fishing tool comprising a shank and a transverse head, the head being insertible into the support through the slot, and the tool being, rotatable to dispose the ends of the head between the arms and the table, the tool being mounted to reciprocate in the support and the hem? being of less height than the distance. the tabie and arms, whereby, when s r ciprecat'ei, afierit has been head will (2011mm; with fihe and the table and effect a, jarring ef the supperfi.
